ATTORNEYS Patented Feb. 21, 1933 UNITED STATES PATENT OFFICE LEWIS A.JARVIS, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR T W. B. JARVIS COMPANY, OFGRAND RAPIDS, MICHIGAN CAP FOR RADIATOR NECKS AND THE LIKE Applicationfiled March 14, 1932. Serial No. 598,747.

The main objects of this invention are: First, to provide an improvedcap for radiators, gasoline tanks and the like which may be quicklyopened and closed and when closed provides an edective seal.

Second, to provide a cap or closure of this type which may be readilyapplied to standard types of motor vehicles.

Third, to provide a cap or closure of this type in which the parts areso assembled that they are not likely to fall or drop into the radiatoror tank on which the cap is used.

Objects relating to details and economies of my invention will appearfrom the description to follow. The invention is defined and pointed outin the claims.

A structure which is a preferred embodiment of my invention isillustrated in the accompanying drawings, in which:

Fig. l is a vertical section of a radiator cap embodying the features ofmy invention, taken on line 11 of Fig. 2, the cover being closed.

Fig. 2 is a'perspective view, showing the cover in its open position.

Fig. 3 is a detail section of the cover.

Fig. 4 is a perspective view of the hinge member.

' Fig. 5 is a perspective view of the gasket backing disk.

Fig. 6 is a perspective view of the gasket.

Fig. 7 is a perspective view of the screw and gasket support assembly,and i Fig. 8 is a fragmentary detail section of the body member, showingthe set screw for securing the body member to the neck of a containersuch as a radiator.

In the accompanying drawings, 1 represents a radiator neck of theexternally threaded type, but it is desired to point out that myimprovements are readily adapted for radiators or the necks of tanks ofthe bayonet type. I have not, however, shown such an adaptation asjoints of that type are well known in the art.

The end 2 of the neck 1 constitutes a seat for'the gasket 3 which issupported by'the downwardly facing shoulder 4 of the closure body member5. A set screw 6 is provided 50 for locking the body member upon thethis support being stepped or shouldered to threaded neck, the bodymember being preferably permanently attached to the neck. The same wouldbetrue if a-bayonet'type of joint were provided between the body memberand the neck.

The body member is provided with an upwardly facing convexly curvedannular gasket seat 8, the gasket 9 being supported for coaction withthis gasket seat betweenthe H- resilient closure diskll and the steppedsupport 10. i I

The gasket itself is preferably of a yielding resilient materialalthough it is yieldingly supported by the resilient closure and aneffective seal is provided when it is made of quitehard material such,for example, as fiber. V

'The'support 10 is secured to the cover 12 by means of the screw 13, thehead 14 of which is disposed within the support 10. A retaining disk 15is secured to the support preferably by the rivet 16, this disk having acentral tool opening 17 of such diameter as to prevent the screwpassingtherethrough,

so that the screw is rotatably secured or 'swiveled to the support.

The cover 12 is provided with an annular stud 18 into which'the reducedportion or smaller portion of the support is engaged,

project into the stud and to support the disk which is arranged on theend of the stud and has a central openingregistering with the stud. Thesupport also has a shoulder which properly'centers the gasket. Thisassembly 35 also secures the cover to the annular hinge member 20, theopening of which receivesthe stud, the hinge member having a pintle 21engaging the vertically elongated pivot hole 22 in the pintle ear 23 ofthe body member. This arrangement permits a limited vertical movement ofthe cover when it is closed.

The cover is locked in its closed position and clamped upon the gasket 9by means of the cammed keeper lugs 24 projecting from the body member tocoact with the slots 25 in the latching lugs 26 on the depending rim orskirt 27 of the cover. v i

The cover is also provided with internal spaced stops 28 which limit therotative movement of the cover relative to the body member. The cover isquickly released or locked by a rotative movement thereof, and at thesame time provides an effective joint or seal.

The parts are so assembled that there are no small parts to drop intothe radiator or tank should they become loosened or detached. The screw,being swivelly attached to the support, is not easily lost and cannoteasily drop into the tank, the openings of which are ordinarily of adiameter exceeding the support. The parts are so related thata singlescrew is all that is required.

I have illustrated and described my improvements in an embodiment whichI have found very practical. I'have not attempted to illustrate ordescribe certain embodiments or adaptations contemplated as, it isbelieved that this disclosure will enable those skilled in the art toembody or adapt my improvements as may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is: l

1. The combination with a body member having an upwardly facing annulargasket seat, of an annular hinge member pivoted to said body for limitedvertical movement when the cover is closed, 'a cover having an annularstud disposed in said hinge member and rotatable therein, a resilientclosure disk disposed on the end of the stud and havingcentral openingsregistering with the opening in the stud, a gasket having a centralopening therein larger than said closure disk disposed on the undersidethereof, a support member having a central part disposed through saidopening in said closure disk and engaged within said stud, said supportbeing shouldered to engage said closure disk and said gasket, a screwthreaded into said cover and having a head disposed within said supportmember, a retaining disk secured to said support member and having atool opening of a less diameter than the head of the screw whereby thescrew is rotatably retainedwithings registering with the opening in thestud a gasket having a central opening therein larger than said'closuredisk disposed on the underside thereof, a support member having acentral part disposed through said opening in said closure disk andengaged within said stud, said support being shouldered to engage saidclosure disk and said gasket, a screw threaded into said cover andhaving a head disposed within said support member, and a retaining disksecured to said support member and having a tool opening of a lessdiameter than thehead of the screw whereby the screw is rotatablyretained within the suport.
